Abstract: Decorative foil comprises a coating layer comprising polyamide composition, where the polyamide (50-100 parts by weight) is obtained from the monomers of diamine (70-100 mol.%) such as m-xylylidene diamine or p-xylylidene diamine; 6-14C-diamine (0-30 mol.%); aliphatic 10-18C-dicarboxylic acid (70-100 mol.%); 6-9C-dicarboxylic acid (0-30 mol.%); and polyamide (0-50 parts by weight). An independent claim is included for a composite part comprising the foil and a substrate.

Abstract: The present invention relates to high-transparency plastic materials which are laser-markable and/or laser-weldable due to a content of nanoscale laser-sensitive metal oxides. These plastic materials, which may be provided as molded bodies, semifinished products, molding compounds, or lacquers, particularly contain metal oxides having particle sizes from 5 to 100 nm and a content of 0.0001 to 0.1 weight-percent. Typical metal oxides are nanoscale indium-tin oxide or antimony-tin oxide. These materials may be used in particular for producing laser-markable production products.
